Samsung may have only just wrapped their copyright issues with Apple, but it looks like they've already ruffled more feathers. At IFA this past week, Samsung showed off a prototype dual-display Windows 8 Ultrabook, and ASUS is the unhappy party this time around.

Back in June of this year, ASUS unveiled their Tiachi tablet, which combined a Windows 8 Ultrabook with a pair of full-HD IPS displays. Consequently, the Taiwanese manufacturer seems to think Samsung's latest is a bit too similar in style and they're voicing their displeasure. According to Digitimes, ASUS CFO David Chang was defensive when asked about the device and stated that the company is evaluating the product in order to determine whether any infringement took place.

In addition, Chang noted that the Tiachi's innards are different than previous ASUS products and that it is unlikely to have been copied. However, they still plan on investigating the matter further once the prototype is made official.

Although Samsung's courtroom woes with Apple may have increased the susceptibility of lawsuit, a dual-display device isn't exactly novel and there may be no case at all. Either way, we'll have to wait till the device goes official but we can be sure that ASUS will also be paying close attention as well.
